DRAWNG BOARD AND STAND.

Application filed lDecemoer 9, 1919.

To @ZZ whom it may concern Be it known that l, MICHAEL Ellllinnnnn,citizen ot the United States, residing at Viroodhaven, in the county otQueens and State of New York, have invented certain new and usefulimprovements in Drawing Boards and Stands. ot which the following is aspecification,

rllhis invention relates to an improved drawing board and stand and hasas one ot its principal objects to provide an arrangement wherein thedrawing board will be constructed to carry a supply roll and wherein thedrawing paper may be shi'lted across the board from said roll.

il. further object of the invention in this connection is to provide aconstruction wherein drawing paper will be held taut across the board soas to eliminate the necessity 'for the use of thumb tacks.

A still 'further object ot the invention is to provide a drawing boardhaving a bed plate or board proper which will not warp and wherein saidplate may, as occasion may demand, be readily renewed.

A still further object of the invention is to provide a constructionwherein the board may be adjustably tilted and may also be adjustablyrotated.

And the invention has as a still further object to provide anarrangement wherein the eiliective height ot the stand may be adjustablyvaried 'tor either raising or lowering the board.

@ther and incidental objects will appear hereinafter.

serial no. aliases;

end sections includes pair of legs joined by spaced rails and, in likemanner, each ot the side sections also includes a pair ot legs joined byspaced rails. Countersunk in the legs oitx the side sections are, asparticularly shown in Fig, 6, vertical plates l2 from the upper endportions ot which project studs 13 and secured to the legs of the endsections are angle plates le in each of which is formed a series ofopenings l5. rlhe openings 15 oi' the alates 11i are adapted toselectively receive the studs 13 and formed through the angle plates arevertical slots l@ adapted to freely receive clamping screws 17therethrough, these clamping screws being threaded through the lower endportions oi' the plates l2. rfhus, as will be perceived, the studs 13orp the end sections may be selectively engaged in the series oiopenings 5 olE the plates ll ot the side sections for adjustablyelevating the side sections, as shown in Fig. l, upon the end sections,when the clamping screws .1 7 may be tightened for securing the sidesections in elevated position. ln this way, 'the effective height ot thestand may be adjustably varied.

The drawing board employed includes a trame comprising side rails 18 andend rails i9, a mullion 2O extending transversely hetween the side railsat a point substantially midway between the end rails. Suitably securedto the end rails are channel strips which, for convenience, have beenindicated at 2l and 22 respectively. Secured to tie side rails ot thetrarne are longitudinal cleats 23 provided with beveled inner enges andoverlying the traine to entend between the channel strips thereofY isthe bed plate 2st of the board. This bed plate is 'provided with beveledside edges mating with the beveled inner edges ot the cleats so that theplate is thus firmly held in position upon the trame. Screws or othersuitable fastening devices are employed tor securing the cleats so that,as will be seen, by removing either of the cleats the plate may bereadily removed, this construction providing an arrangement whereby theplate may be renewed from time to time as occasion may demand. rlheplate is preferably constructed of what is generally known ascomposition' board although other approved material may be employed.However, in providing a plate of the character indicated, said platewill not warp.

ln the strip 2l is formed a vertical slot 25 to freely receive thevertical flange of a clamping plate 26, so that the horizontal flange ofsaid plate will, as particularly shown in Fig. 2, overhang the channelof the strip. lepending from the clamping plate adjacent opposite endsthereof are studs 27 which are freely received through the strip andthrough suitable wear plates 28 connected thereto, and threaded upon thestuds are suitable wing nuts 29 confronting the wear plates. As will beobserved upon referencefto Fig. 4, the upper end portions of the studsextend over the horizontal fiange of the clamping plate7 providing areinforcement therefor. Secured to the ends of the channel strip 22 arebearing plates which, for convenience, have been indicated at 30 and 31respectively. These bearing plates are provided at their inner sideswith laterally directed arcuate stop flanges 32 lying within the channelof the strip and, as will be observed, the end portions of said flangesat the upper side of the channel are rounded off. (lournaled upon thebearing plates to lie within the channel of said strip is a talreuproller 33 extending axially between said fianges. At one end the rolleris equipped with a ferrule 34 journaled through the plate 30 whilefatits opposite end, said roller is equipped with ferrule 35 from whichprojects a suitable trunnion journaled through the` plate 3l. Fixed uponsaid trunnion at the outer side of the plate is a ratchet disk 36 andpivoted upon. the plate to cooperate with said disk is a pawl 3'?.Seated against the disk 36 is a winged turning' head 38 also suitablyfixed to the trunnion of the ferrule 35 so that by turning said head theroller 33 may be rotated. Formed in said roller at one side thereof is alongitudinally extending channel 39 and normally engaged in this channelis the vertical flange of a substantially T- shaped locking" strip 40.At the mouth of the slot 39 the roller is flattened to seat thehorizontal ange of the locking strip and, as will now be observed, thislatter flange extends beyond the ends of the vertical flange of thestrip to overlie the ferrules 3ft and 85 of the roller. ln use, a supplyroll of drawing paper is placed within the channel of the strip 21. thepaper strip il being wound about a suitable core 4:2. By removing theclamping plate 26 the supply roll may, of course, be readily fitted inposition and, as will be observed, by adjusting` the wing nuts 29, theplate may be caused to bear against the roll for tensioning the rollwithin the channel of the strip. At its free end, the paper strip is ledacross the slot 89 in the take-up roller when the locking strip 40 is,as shown in Fig. 5, fitted in position upon the roller for connectingthe strip thereto. Then., by turning the roller, the

end portions of the strip will be moved into coacting relation with thestop flanges 32 so that the strip will, while the first complete turn ofthe roller is made, be held upon the roller by said flange, the endportions of the strip riding upon the flanges and being held therebyflat against the ferrules of the roller. After the first complete turnof the roller is rnade7 the paper strip will then overlie the lockingstrip so that the locking strip cannot then become dislodged from theroller. Accordingly, as will be seen, the turning head 38 may beoperated to wind the paper strip from the supply rollr across the bedplate of the drawing board onto the take-up roll and since the clampingplate 26 will retard unwirfding of the supply roll while the ratchetdisk 36 and pawl 37 will prevent counter-rotation of the take-up roll?the strip will be held taut lying flat against the bed plate.Accordingly7 any necessity for the use of thumb tacks will be elimi-'nated while the paper strip may be readily shifted to present, asdesired, a'clean or unused surface over the bed plate of the board.

Removably rested upon the stand is a supporting frame for the drawingboard. This frame includes a lower frame section 4.3 and a mating upperframe section 44. The frame section 43 is constructed to mate with thetop rails of the stand and is provided with depending side strips 45adapted to coact with the outer faces of said rails so that said sectionwill firmly seat upon the the stand. At the forward side of thesupporting frame, the sections thereof are swingingly joined by suitablehinges con nected to the forward side rails of said sections so that, asshown in Fig.v l, the upper section may be tilted upwardly and forwardlyupon the lower section and to prevent possible accidental raising' ofthe rear side portion of the lower section, the rail of this sectioncarries a hool'tG engageable in an eye 47 upon the upper rail ofthe'rear side section of the stand. Extending between` the side rails ofthe lower section 43 are spaced transverse mullions 48 in the upperVedges of which are formed, at the rear end portions of the mullions,series of notches 49. The upper frame section carries a longitudinalmullion 50 and swingingly mounted upon this mullion is a prop 51, thespaced legs of which are adapted to coact at their free ends with theseries of notches 49. Countersunk in the mullion 20 of the frame of thedrawing board is a plate 52 to which is fixed a post 53 depending fromthe plate and rotatably engaged through the mullion 50 of the upperframe section 44:. Threaded upon the lower end portion of the post is awing nut 54 and surrounding said post is a helical spring 55 heldbetween washers 56. rlhus9 the post 53 will rotatably connect thedrawing board with its supporting frame while the wing nut 54 may beadjusted for tensioning the spring 55 so that the uppermost of thewashers 56 will be held in binding contact with the lower 'face of themullion for frictionally resisting rotation of the board. Consequently,the board may, as suggested in Fig. l, be rotatably positioned asdesired when the board will be firmly held in such position, and byswinging the frame section lil upwardly upon the .trame section 43, thedrawing board may be adjustably elevated when the prop 5l will coactwith the series ot notches 49 in the mullion 4:8 of the lower tramesection Jfor sustaining the board in inclined position. It willaccordingly be seen that I have provided a particularly effectiveconstruction for the purpose set forth. rIhe drawing board may, ifdesired, be readily detached from its supporting frame while the board,together with said frame, may be bodily removed from the stand. Further,as will be clear, the stand may be easily collapsed so that when not inuse the drawing board and stand may be arranged to occupy a minimumspace.

Having thus described the invention, what is claimed as new is:
